Kit consisting of 2 rear shock absorbers, original height, eye/pin, with 50 mm body, pressurized double-tube type, which can be revised and adjusted according to your needs.
The shock absorbers of our kit, 100% Made in Italy, are built with steel tubes for mechanical use internally lapped and fully galvanized to avoid corrosion.
The bushings are made of polyurethane, very resistant to deformation and wear.
All components are sintered for maximum calibration control and the seals are in graphite Teflon to improve smoothness and silence.
The shock absorber can be recalibrated and overhauled in all its parts and in the first year after purchase the recalibration is carried out free of charge according to your needs.
Inside the shock absorber there is a first internal bump stop in extension resistant up to 5000 kg and a second polyurethane bump stop that slows down the last 10 mm of stroke to avoid excessive stress on the frame supports; these limit switches can be used as a travel limit for the axle.
For the realization of the shock absorbers we at HM4X4 use ROTHEN oil with a high viscosity index, which guarantees the maintenance of the calibration up to 200 °C, making them suitable even for heavy use and raids in the desert.
The overhaul of the HM4X4 shock absorber is guaranteed at a cost of 40.00 euros each.
The pressurization is carried out with the innovative AIR DRYED technique which allows to pressurize the shock absorber with inert gas, after having created a high vacuum, completely extracting air and humidity from its interior. This allows to minimize the phenomena of oil emulsion and the creation of rust that humidity inevitably creates inside a non-pressurized shock absorber. In addition to making the shock absorber more performing, the Air Dryed pressurization considerably extends the duration of the shock absorber over time and guarantees constant calibration even after years of use.
